1. A reference to electrotonus or the altered condition of a nerve or muscle during the passage of an electric current through it.
2. The modified condition of a motor nerve under the influence of a constant galvanic current.

A current induced in a nerve sheath without the creation of a new current by an action potential or a momentary change in electrical potential on the surface of a neuron or muscle cell.

An altered condition of excitability of a nerve or muscle which is produced when it is in the electrotonic state.

1. The potential led off by electrometers on either side of bipolar electrodes when a nerve is being stimulated by direct current.
2. The potential developed by cells as a result of metabolic activity and circuited (path for electrical current to flow) through surrounding tissue.

A gap junction which transmits electrical impulses in electrically excitable tissue.

A gap junction is an intercellular network of protein channels that facilitates the cell-to-cell passage of ions, hormones, and neurotransmitters.
